I could test successfully on RISC-V, booting from MMC on a command line 
shell, and testing i2c4. However, I have an issue with Ethernet. When I 
add "ip=172.24.0.2" (for example) to the kernel command line, I'm 
getting this:

[    2.586984] stmmaceth 4070000.ethernet eth0: Register 
MEM_TYPE_PAGE_POOL RxQ-0
[    2.596428] stmmaceth 4070000.ethernet eth0: cannot attach to PHY 
(error: -ENODEV)
[    2.627351] IP-Config: Failed to open eth0
[    2.631859] IP-Config: No network devices available

However, "eth0" appears in the list of networking devices.
Does this work on your side?
Cheers
Michael.
